Here is a link to Mapquest so you can get an idea of the area.
Here is Rt 2 for anyone that doesnt know.
The gray arrow is the center of Charlemont MA. That is the beginning of the good section of Rt.2
The Yellow Arrow is Whitcomb summit where the best part of Rt. 2 comes to an end. A little further up the road is a hairpin turn. It has always been greasy, but the approach and exit are a blast!
The white arrow points to the fun section of Rt. 2 which just happend to be paved this summer.
If you look to the right of the yellow arrow, you will see a road that runs down toward the river. This is an extremely steep and scenic road which is fun to ride down, turn around, and come back up.
The blue arrow points to a road that follows the river which can be reached by starting at the gray arrow, or by the steep road that I just mentioned. It passes by a number of hydroelectric plants, a decomissioned nuclear power plant, and the Hoosic Tunnel. The road eventually joins up with Rt. 100 in Vermont.
Although the picture doesn't show it, Rt. 2 runs between, over, and through the mountains in the area, so its a sight that must be seen. I like the route so much that my daily rides over the summer always start with this section.
